I just had some installed. ~~Guaranteed 80% efficiency for 20 years.~~ I heavily doubt they will last 60 years.

Had energy storage installed as well. Only guaranteed 90% (~4500 cycles) for 10 years.

EDIT: double checked the data sheet. They are actually 86% for 25 years with a rated 0.5% per year degradation rate.

Quite sure mine had 30 years at 90 % . But it was the really good mono ones. Storage is a completely different story. But hey even if they are down to 25% I would keep them and just add new ones.

0.5 would mean 30 for 60 years also..
